虽然预防自杀是国家的优先事项，特别是在服务人员和退伍军人（SMV）中，但对自杀相关结果的理解仍然很差。以人为本的方法（例如，潜在类别分析）有希望在较大的人群中确定独特的风险概况和亚组。目前的研究确定了潜在的亚组，其特征是先前的自我导向的暴力史和自杀未遂幸存者中自杀的近端风险因素，并比较了人口统计学和最致命的企图特征的亚组。参与者包括平民和SMV报告终身自杀企图（S）（N= 2643）从军事自杀研究联盟。两个类出现了共同的数据元素：自杀企图和非自杀自伤频率，自杀企图的方法，未来自杀的可能性，自杀披露，自杀意图，以及企图的预期和实际的致命性。高风险历史类的特征是更大的死亡意图，对企图死亡和方法致死的确定性，相信伤害在医学上是不可修复的，以及先前非自杀性自伤的可能性。低风险历史课的特点是对死亡和方法的矛盾心理更大。高风险类别的成员更可能是男性，老年人，SMV，正规教育较少，使用枪支作为最致命的尝试方法，需要更高程度的医疗照顾。低风险类成员更可能是女性，平民，使用切割作为最致命的尝试方法，并且尝试时需要较少的医疗护理。研究结果对风险评估有影响，并强调了对自杀行为的主观看法的重要性。有必要对实时个人水平进行进一步调查，特别是对于可能处于潜在致命自杀行为风险最大的SMV。
While suicide prevention is a national priority, particularly among service members and veterans (SMVs), understanding of suicide-related outcomes remains poor. Person-centered approaches (e.g., latent class analysis) have promise to identify unique risk profiles and subgroups in the larger population. The current study identified latent subgroups characterized by prior self-directed violence history and proximal risk factors for suicide among suicide attempt survivors, and compared subgroups on demographics and most-lethal attempt characteristics. Participants included civilians and SMVs reporting lifetime suicide attempt(s) (n= 2643) from the Military Suicide Research Consortium. Two classes emerged from Common Data Elements: suicide attempt and non-suicidal self-injury frequency, suicide attempt method, perceived likelihood of future suicide, suicide disclosure, suicide intent, and perceived and actual lethality of attempt. A Higher-Risk History class was characterized by greater intent to die, certainty about attempt fatality and method lethality, belief injury would be medically unfixable, and likelihood of prior non-suicidal self-injury. A Lower-Risk History class was characterized by greater ambivalence toward death and methods. Higher-Risk class members were more likely to be male, older, SMVs, have less formal education, use firearms as most-lethal attempt method, and require a higher degree of medical attention. Lower-Risk class members were more likely to be female, civilian, use cutting as most-lethal attempt method, and require less medical attention for attempts. Findings have implications for risk assessments and highlight the importance of subjective perceptions about suicidal behavior. Further investigation of real-time individual-level is necessary, especially for SMVs who may be at greatest risk for potentially lethal suicidal behavior.
